creating a sustainable food future

A menu of solutions to sustainably feed more than 9 billion people by 2050

The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on...

COPENHAGEN//WASHINGTON — The World Resources Institute (WRI) today announced the first step in designing a global standard for measuring food loss and waste. The forthcoming guidance, called the “Food Loss and Waste Protocol,” will enable countries and companies to measure and monitor the food loss and waste that occur within their boundaries and value chains in a credible, practical, and consistent manner.

Innovative farmers are beginning to demonstrate how agroforestry and other relatively simple practices can significantly boost food production in Africa’s drylands. In fact, according to a new WRI working paper, improving land and water management on just 25 percent of sub-Saharan Africa’s 300 million hectares of prime cropland would result in an additional 22 million tons of food. This strategy could go a long way towards sustainably feeding Africa—and the world.

We examination the role of four improved land and water management practices and the effect they could have on smallholder crop yields and livelihoods in Sub-Saharan Africa. We also provide a series of recommendations for how to scale up these practices.

Creating a Sustainable Food Future, Installment Three

The United Nations projects that world population will rise from just over 7 billion in 2012 to nearly 9.6 billion by 2050. This paper examines the nature of the population challenge globally, the effect of population growth on food demand in Sub-Saharan Africa, and the potential benefits―in...

The United Nations’ new population growth projections show that the world is set to reach nearly 9.6 billion by 2050. This growth holds serious implications for global food security. Absent other effective measures to control dietary shifts and reduce food loss and waste, the world will need to produce about 70 percent more food annually by 2050 to meet global demands. That is a big task, and even harder to do without converting millions more hectares of forests into farmland, contributing to climate change.

How can the world feed more than 9 billion people by 2050 in a manner that advances economic development and reduces pressure on the environment? Answering it requires a “great balancing act” of three needs—each of which must be met simultaneously.

About 24 percent of all calories currently produced for human consumption are lost or wasted. We examine the implications of this amount of loss and waste, profiles a number of approaches for reducing it, and puts forth five recommendations for how to move forward on this issue.

An amazing 24 percent of all food calories produced today go uneaten. Reducing this loss and waste is a critical step toward generating enough food for a population set to reach more than 9 billion by 2050.

Fortunately, there are low-cost methods that can begin saving food immediately in both the developing and the developed world. WRI’s new working paper, Reducing Food Loss and Waste, identifies a number of these strategies. Some methods cut loss “close to the farm,” while others reduce waste “close to the fork.”

Reducing Food Loss Close to the Farm

Improved storage methods

Simple, low-cost storage methods can drastically cut food loss, especially for small-scale farmers in the developing world, who frequently lose food to factors like pests, spoilage, and transportation damage. For example, a system developed by researchers at Purdue University in which grain is stored in three interlocking plastic bags locks out pests and keeps grain fresh for months. The Food and Agriculture Organization has built more than 45,000 small, metal storage silos—just big enough for use by a single farmer—in 16 different countries. These silos have cut food loss during the storage phase to almost zero. Even using a plastic crate instead of a plastic sack during transport can cut loss dramatically by preventing bruising and squashing.
